Quantitative Properties: Color: Colorless gas; pale blue liquid State: non metal called chalcogen, gas Texture: none
Quantitative Properties: Melting Point: -218.79 °C, -361.82 °F Boiling Point: -182.95 °C, -297.31 °F Density: 1.429 g/L
Where its found: EVERYWHERE
Discovered: Oxygen was discovered in 1771 by Carl Wilhelm Scheele and later on uncovered further by Joseph Priestley in 1774. Their discoveries with this gas had paved way for further studies about the importance of oxygen as well as digging information about its physical properties.

Origin of symbol/name: From the Greek words oxus (acid) and gennan (generate)
Bohr Diagram:
Ion charge: O2- because Oxygen is in group 6 (6-8=-2) So it charge is O2- Compound: Water (H2O) is a compound of hydrogen and oxygen. Carbon Dioxide (CO2) is a compound of carbon and oxygen.
Common uses:
Breathing. Therefore, oxygen therapy is used for people who have trouble breathing due to some medical condition (such asemphysemaor pneumonia).
Oxygen gas is poisonous to bacteria that causes gangrene. Therefore, it is used to kill them.
Pure oxygen is used to ensure the complete combustion of different chemicals.
Oxygen is used to treat water and cut and weld metals.
Reaction: ... with phosphorus. White phosphorus catches fire spontaneously in air, burning with a white flame and producing clouds of white smoke - a mixture of phosphorus(III) oxide and phosphorus(V) oxide. (P4o10) ... with sodium. Small pieces of sodium burn in air with often little more than an orange glow. Using larger amounts of sodium or burning it in oxygen gives a strong orange flame. You get a white solid mixture of sodium oxide and sodium peroxide.
DID YOU KNOW? Concentrated oxygen promotes fast combustion. While a spark or heat is still needed to start a fire, having concentrated oxygen near various fuels can be very dangerous.
Also... The sun’s mass is made up of around 1% oxygen!
